All eyes have been on Princess Beatrice since reports emerged of a relationship with 35-year-old property developer Edoardo Mapelli Mozzi, and it looks like they just made it official during a gala on Tuesday night.

Beatrice, and her reported boyfriend arrived at London's National Portrait Gallery, where the two showed off their royal couple style.
